To all lwhom it may concern.

Bc it known that I, SIDNEY lV. SINS- Hmirnn, a citizen of the United States, residing at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Fluid- Treating Systems and Elements Thereof for Centrifugal Separatore; and I do hereby declare the following to be a full, clear, and exact description of the invention, suchA as will enable others skilled in the art to which it appertains to make and use the same.v

.This invention relates to improvements in fluid treating systems, and elements thereof, for centrifugal separators.

The invention may be employed with any substance, centri'fugally acted upon for separation purposes, wherein the substance is treated or sprayed with a fluid or liquid,

chemically impregnated or otherwise, still 'the primary use i'or which I haye designed the same particularly relates to the treating or washing of sugar, for freeing the same from molasses and impurities.

At the beginning, it may be stated, that throughout the specification and claims, in using the terms I air under regulated pressure, and treating Huid orliquid, I do not limit myself to the specific use oi air or Water, employed in sugar washing, for any elastic liuid, such as gas, might be employed, or treating fluids7 or liquids, other than water might be used to advantage in the chemical treatment oi" certain substances, and it will be understood, therefore, that these terms used for simplicity, are intended to cover a full range of equivalents.

Also, it will be understood that the `invention is not limited to thc specific use mentioned, but as the structural arrangement and principles involved are always substantially the same, for the purpose of simplicity, I shall so illustrate and desci .be it as applied to a centrifugal sugar separator.

Generally speaking my invention consists oi certain novel elements combined in a simplified system, for delivering a predetermined quantity Oi the treating fluid (such as water in sugar washing) to the contents of a centrifugal separator, the quantity of which iiuid is automatically measured by a uniform measuring pot, provided with mcchanical means which may be set tor regulating the amount of delivery as predetermined, and which Huid is also delivered under a regulated pressure, subject to'change at will.

The primary object of the invention, therefore, is to set a measuring device to automatically regulate the delivery of the desired quantity of treating fluid, under a regulated pressure.

A second object is to provide a particular form of measuring receptacle or pot, which is of uniform size, and contains means which may be adjusted to any degree to measure a predetermined quantity of treating fluid, and regulate its delivery.

A further object is to provide an arrangement, whereby a local controlling' device, occupying inconsequential space, may be installed at the place ot use, near the centrifugals, while the supply tank and measuring pot may be remotely removed, which would probably be desirable in large plants.

A still further object is to avoid the use of flexible connections or couplings, such as hose pipe now commonly employed in similar relations, and to simply provide rotating metallic joints or couplings, for the main control, the measuring pot control, and the spray or delivery nozzles.

With these and other objects in view,l the invention consists of certain novel elements and the structural arrangement and combination of parts, as will be more fully described in the following specification and particularly claims.

It will be obvious that the invention is not limited to the exact details as shown and described, norto the specific use oi sugar washing, still i'or the purpose of a complete disclosure, reference is had to thc accompanying drawings illustrating a practical cmbodimcnt of thc invention, in which drawings like characters designato the same parts in the several views, and in which- Figure 1, is an assembled view of the salient elements of the system. Fig. 2, is a top plan view, partly in horizontal ,section on the line 2 2 of Fig. El. 3, is an elevational View of the measuring pot, showing the operating handle and indicator for the adjustable branch i'ecd pipo, und partly in vertical section showing the interior arrangement of said pot. Fig. l, is a fragmentary plan view of thc top of the sugar basket and its containing receptacle, and showing the mounting of the spraying nozzle. Fig. 5, is

pointed out in the appended Sti , vation -of a pair of three-way valves, operated simultaneously by a single lever, and controlling respectivelythe air supply and i the treating liquid supply. Fig. 7, is a side elevational view of the air valve arrangement, looking at the same in the direction of the arrow 7 in Fig..6. Fig. 8, is a sec` Vtional detail view, of the liquid cock thrown to a position opposite to that shown in Figs.

6 and 7 and with communication open between the supply tank and the measuring pot, Eind Fig. 9, is a similar view of the air cock, set with communication open between the top of the measuring pot and the relief pipe.

Describing my invention in detail, with reference to a vsugar separator, although not so limited in use as heretofore stated, 1 designates the usual outer receptacle for receiving the thrown off molasses and water, and which is provided with. a discharge outlet, not shown.

2 is a flanged annulus', disposed internally af the outer receptacle, and yrecessed to receive a flat ring 3, on which is fixed a bearing support et for mountng the spraying nozzle 5 communicating with the liquid treating pipe line, through a rotary valve connection, not shown in detail, but indicated at 6, the position ofthe nozzle 5 in full operative position'being shown in full lines in Figs. 1, l and 5, and in Fig. 5 .it 1s shown dotted, in substantially'horizontal position to begin spraying, and in vertical position, where the flow is completely shut off. The openin(1r and closing of the nozzle valve is controlled by the swing of the nozzle.

7, designates the sugar basket, which is of the usual type, having an upwardly Haring internal top flange 8, and a foraminous or reticulated cylindrical wall 9, through which the molasses and water are thrown into the receptacle 1 by centrifugal force, as the basket is rapidly rotated on a vertical axis.

10 indicates the sugar line.

In Fig. 1, the centrifugal separator is simply shown conventionally, but of course it is provided with an internal rotary basket asin Fig. 7. A

These parts in themselves form no essen` tial novel feature of the invention, although it is beneficial to have a rotary mechanical coupling,`including a control valve, between the nozzle and the pipe line, instead of employing ahose pipe connection as is custoinarily done.

Referring now' to Figs.` 2 and 3, which illustrate in detail the principal essential vfeature of the system, 11 designates a container, which l-refer to as the measuring pot, providedwith a closed' lid 12, securely bolted thereon, and may have a drainage ta 13 atthe bottom to.;remove accumulated sedi-fl.v

nient. This container' has the bosses 14 and 15, oppositely disposed, on its outer surface,

of the pipe 17, and also close the outlet'to fst -with a plug 22, to take up the end thrust prevent leakage from the container, the end ofthe pipe itself being plugged or otherwise capped or closed. i

The pipe 17 is formed of two sections, connected by a T-coupling 23, in the third open..

ing of which is threaded a vertically swmgf',

Ving branch feed pipe 24, varied positionsi,o'fv this feed pipe being shown in full and dotted p' lines in Fig. 3, the purpose of which will bev hereinafter fully referred to.- In order te adjust this branch feed pipe 21 to any desired position in the containerfor measuring pot, I provide an operating handle 25', alixedr to the protruding portion of the pipe 17,

l which latter terminates in a fluid tight rotary connectionwith the elbow joint 26,1eadmg to lthe liquid pipe line hereinafter referred to.

Secured to the inner face of the flange head 20, by the rivets or screws 27, is a scaled segment plate 28, with which coperaties apointer 'or indicator finger 29, carried by a sleeve 30, fixed to the pipe 17 to rotate therewith and indicate the measured amount of liquid, say for instance in gallons, to be discharged, dependent upon the position or angle at which the branch pipe 24 posed in the measuring pot.

which may be controlled by a float .operated valve arrangement '31 is a compressed air tank or source of compressed airsupplyf,

and 35 shows conventionally an air pressure regulator, of any suitable type, to Acontroll ria the degree of pressure at which the air is delivered to the measuring pot.- 'At 36 I- have shown a supporting plate or shelf between a pair of separators, which is 0.011 veniently located, butI which is merely shown by way of illustratiem Above the support 36 is mounted a pairgof three-way valves 37 and 3S. This pair of'fvalves is operated a single lever 39a, which when,-.thrown 1n the position shown in Figs. 6 ,and y7, opens conn.,`

mun'ication betweenoneset of ports with the4 pipe lines, to open communicatlon between the compressed air tank and the top of the measuring pot, and between the liquid in the measuring pot and the spray nozzles, to per mit of spraying under regulated pressure; and when thrown in the opposite direction, opens communication between the supply7 'ank and the measuring pot, and also from the top of the measuring pot to the atmos plier-e. These valves 37 and 3S may be re-v ferred to, respectively` as the air and the liquid control valves. Each comprises a easing, provided with a rotary plug having; respeetivelyE the communicating ports 39, l() and il, of the air valve, and 43 and Lelfi, of the liquid valve. The air valve casing E? has lthe central branch 45, and the end branches 46 and al?, While the liquid valve casing has similar branches 4:8, i9 and 50, which connect with their complementary pipes of the system, designated by the same numerals.

To now trace out the lines of piping:-l The cover l2 of the measuring pot is tapped centrally at 5l, and from this tap a pipe lll leads directly to one branch of the air Valve; from the central branch of the air 'valve S7, a pipe l5 leads to the air pressure regulator and from the third branch oli the valve, the pipe i7 leads ug to the liquid supply tank 'and terminates just above the liquid line therein. From the elbow 2li of the trunnioned pipe l?, the pipe 50 leads to the rear end orliraneh of the liquid valve 38; the pipe 49 leads from the other end branch ot the valve 3S to the spray nozzles while the pipe 48 leads from the supply 'tank 3l to the central-branchof the valve easing; 38.

From the foregoing Complete description, it is believed that the advantages and operation of my invention will be fairly understood, but itinight he said that1 the measured quantity of treating liquid haring heen delivered, es shown in Fig. 3, where the level of the treatin-'9' liquid has rearhed a position incident with the lowered position oi the normally submerged end the branch feed pipe 24, the measuring' pot is .new to be refilled against the pressure of the head oi sir in the pot above the Water or treating lluid. The valve lever is then thrown to the lett` when the three-way valves will more through an angle of forty live degrees into 'the positionsr shown in and 9, wl'iereupon the air in the measuring pot esca througl'i the pipe 4G,

it will be observed that by operating' the handle 25 the branch feed pipe can be set at any angle, to supply a predeteriuined mei sured amount ot thc liquid., as the liquid will onli,T be forrcd therethrough while the end of the pipe illreniains below the surfare of the same. The grauluatifuis on the indicator segment will be so computed that the position ol the pointer will indicate the number oi gallons or other units of measure that will bcdiseharged, owing to the position of the feed pipe in the measuring pot.

It may also be observed lthat hy haring' a central or main Control at the threewray "Valves, and a loeal control at the nozzles, :ny

system is not limited to a single separator, but any nun'ibcr oi' sel'iarators may be coupled up in the swseili, two being` shown in Fig'. l, and only one measuring pot and one supply taai: will. be necessary. Thus one centrifugal can be'operating, 'while another is being unloaded, and still another loaded for treatmeitE and hence considerable loss of time is afe'oi'l" .The partirular arranfI the air and liquid threefway Valve., as shown, is merely by wayof illustration, and the connection of the piping therewith might bc. accoinplished with similar results in suitable way.

devices are manifestly not entirely satisfacn tory and have proven positively inaccurate in practice, and my claims are not directed to any such arrangement, nor to any arrangement wherein the delivery might be partially but ineffectively controlled for instance by a free piston operating in a measuring cylinder. I am not aware, however, oil" any prior systems of this character, in which the same predetermined or measured quantity of discharge may be successively delle ered, withoutresetting the measuring control-element, evcepting,` for the purpose of varying the desired quantity of discharge, as is accomplished by my measuringl pot ar rangement,v operating in conjunction with other essential elements of the combination, which are inseparable features of the improved system, substantially as described. Nor am I aware of such a system even, whereby a charge of the treating' lluid is delivered by the action of ay pressure fluid, the
